Common Causes and How to Resolve

  1. Invalid Payment Method Type:: The value provided in the payment_method_type field is not recognized or supported. How To Resolve: Confirm that the payment_method_type value matches one of the supported payment method types listed in the API reference for the different countries. You can find the full list here.
  2. Spelling or Case Sensitivity Issues: The value of the payment_method_type field contains typographical errors or is in the wrong case. For example, a payment method like Mtn, may need to be passed as MTN, Mtn or mtn depending on the request type. How to Resolve: Double-check the spelling and casing of the payment_method_type field to ensure it matches the expected format. You can find the list of payment method types for collections here and for disbursements here.
